Is is not just politicians and advertisers who need good speaking skills. The media,need people who can speak in clear and convincing way. There are many other professionals who we expect to be able to communicate effectively,sometimes in difficult situations, such as teachers,doctors,psychologists,counsellors and people who work for the emergency services. As well as being good listeners, they need to know exactly when to speak and what to say. And we should not forget that in the world of business, the difference between success and failure means you must get your message across well in meetings or presentations. You may have the best idea, product or service in the world , but before you become a millionaire, you will need to 'sell' your idea by convincing other people.
